3V to 5V Ultrasonic Distance Sensor, Front Header HC-SR04-

Product Overview

PSG04177 is an ultrasonic distance sensor. It has been engineered to work down to 3V making it absolutely ideal to connect directly to Micro Bit or Raspberry Pi GPIO pins using the 3.3V power. Works identically to the standard product although you will notice a little drop off of maximum distance when using lower voltages. This differs mechanically from the HC-SR04 and HC-SR04+ in that the connection pins protrude forward from the PCB instead of backward.

– 3V to 5.5V Operating voltage range, 2mA operating current
– 15° Sensor angle, 2cm to 450cm range, 0.3cm resolution
– Output a 10µs HIGH signal to Trigger input to start the detection
– Measure the length of pulse received on Echo output to determine distance
